PrestaShop 8 & 9 WebP Support: What Merchants Need to Know

PrestaShop 8.2 vs 9.0: WebP (and AVIF) — what actually works

• In PS 8.2 there’s a native WebP toggle, but it’s experimental.
Path: Advanced Parameters → New & Experimental Features → Enable WebP.
Then go to Design → Image Settings → Regenerate thumbnails (All images).

• How it behaves in 8.2
– URLs may still show .jpg/.png, but browsers that support it get image/webp.
– Most thumbnails convert; some originals remain JPG/PNG.
– Requires GD or Imagick with WebP enabled; otherwise PS quietly falls back to JPG/PNG.
– Some themes/modules don’t love the MIME swap.

• Verify quickly
– DevTools → Network → click an image → Content-Type: image/webp.
– Or terminal:
curl -I "https://yourshop.com/img/p/1/2/12-large_default.jpg" | grep -i content-type

• Works in 8.2: regenerated thumbs, WebP delivery in supported browsers.
• Limits in 8.2: no AVIF, inconsistent coverage, confusing file names; many shops still use an optimizer module for full coverage & fallbacks.

• PS 9.0: WebP becomes first-class (not experimental), adds AVIF, and is more consistent across all image types.
